ToggleAre Monstera Toxic to Cats?
Monstera plants are a favorite among lovers for their unique, large, and glossy leaves. However, if you’re a cat owner, you may have concerns about whether Monstera plants pose any risk to your feline friend. Are Monstera toxic to cats? The answer is yes. Monstera plants can be harmful to cats, but let’s dive deeper to understand why and how to keep your cat safe.
What Makes Monstera Toxic to Cats?
Monstera plants, including popular varieties like Monstera deliciosa, contain insoluble calcium oxalates. These tiny, needle-like crystals can cause discomfort and irritation when ingested. When a cat chews or bites into the plant, the crystals are released, causing a burning sensation in their mouth and throat.
While the reaction is generally not life-threatening, it can still cause significant discomfort for your cat. The real danger occurs if a large amount of the plant is consumed, which can lead to more serious symptoms and complications.
Signs of Monstera Poisoning in Cats

If you’re worried that your cat has ingested Monstera, it’s crucial to watch for the symptoms of poisoning. Here are some common signs that may indicate your cat has been affected by Monstera:
- Drooling: The irritation caused by the plant can make your cat drool excessively.
- Pawing at the Mouth: Your cat may paw at their mouth in an attempt to alleviate the discomfort.
- Vomiting: Nausea and vomiting can occur after ingesting the plant.
- Loss of Appetite: A cat may refuse to eat after coming into contact with Monstera due to mouth pain.
- Swelling: Swelling of the tongue, lips, and throat is possible, leading to difficulty in swallowing.
- Oral Irritation: Your cat may show signs of pain when trying to eat or groom themselves.
- Difficulty Breathing: In rare and severe cases, swelling in the throat can cause breathing difficulties.
What to Do if Your Cat Eats a Monstera Plant?
If you notice any of the above symptoms and suspect your cat has eaten Monstera, take action immediately. Here’s what you can do:
- Remove Access to the Plant: Move your cat away from the Monstera plant to prevent it from consuming more.
- Rinse Their Mouth: Try rinsing your cat’s mouth with water to remove any remaining plant material. Be gentle, as their mouth may be sensitive.
- Contact Your Veterinarian: It’s always best to consult your veterinarian, even if the symptoms seem mild. The vet may recommend treatments such as antihistamines or fluids to reduce irritation and support your cat’s recovery.
- Monitor for Severe Symptoms: If your cat is struggling to breathe or showing signs of severe distress, seek emergency veterinary care right away.
Why Do Cats Eat Monstera Plants?
You might wonder, why cats eat Monstera plants in the first place. Cats are natural explorers, and they often use their mouths to investigate their surroundings. A Monstera plant, with its large leaves and tempting texture, may look like a toy to your curious feline.
Cats also sometimes chew on plants out of boredom, or because they lack certain nutrients in their diet. However, this behavior can be risky, especially when the plant in question is toxic.
How to Keep Your Cat Safe from Monstera Plants
Since Are Monstera toxic to cats? It’s important to keep your pet safe. Here are some easy tips to protect your cat:
- Place Plants Out of Reach: Position your Monstera plants in areas where your cat cannot access them. Consider using plant hangers, shelves, or closed rooms to keep the plant out of reach.
- Cat-Friendly Plants: If you want to keep greenery in your home, consider choosing non-toxic, cat-friendly plants such as spider plants, Boston ferns, or cat grass.
- Provide Distractions: Give your cat plenty of toys and mental stimulation to discourage them from chewing on houseplants.
- Train Your Cat: Use positive reinforcement to train your cat to stay away from certain areas, including spots where you keep your Monstera plants.
Alternative Cat-Safe Houseplants

How Much Monstera is Toxic to Cats?
The severity of the reaction to Monstera toxicity in cats depends on how much of the plant was ingested. Typically, small bites or nibbles result in mild symptoms like drooling and oral irritation. However, larger quantities can lead to more serious reactions, including swelling and difficulty breathing.
While a few bites may not be fatal, it’s essential to monitor your cat closely and act quickly if you notice severe symptoms. Always contact your vet if you’re unsure about the situation.
Long-Term Effects of Monstera Ingestion in Cats
For most cats, the effects of Monstera ingestion are temporary, and they recover fully within a few days with proper care. However, repeated exposure to toxic plants like Monstera can lead to chronic issues, including gastrointestinal problems and ongoing oral irritation.
To avoid long-term consequences, it’s best to keep Monstera and other toxic plants out of your cat’s environment entirely. Prevention is the best way to ensure your cat’s safety and well-being.
Common Monstera Varieties and Their Toxicity Levels
Several types of Monstera are popular among plant enthusiasts. Some of the most common varieties include:
- Monstera Deliciosa: The most recognized Monstera species, known for its large, split leaves. This variety is toxic to cats due to its calcium oxalates.
- Monstera Adansonii: Often called the Swiss cheese plant, this smaller variety also contains the same toxic compounds as Monstera deliciosa.
- Monstera Obliqua: A rare variety, but equally toxic to cats if ingested.
No matter the variety, all Monstera plants contain the same calcium oxalates, making them dangerous to cats.
Are Monstera Toxic to Cats? The Verdict

To sum up, Monstera plants are toxic to cats due to the presence of insoluble calcium oxalates. While the toxicity level is generally not life-threatening, the irritation and discomfort caused by chewing or ingesting the plant can be distressing for both you and your cat.
If you have a Monstera plant at home, take steps to protect your cat by keeping the plant out of reach, providing alternative, safe plants, and ensuring your cat has enough distractions to avoid chewing on dangerous plants.
Conclusion
If you’re a cat owner, it’s crucial to be aware of the potential risks that Monstera plants pose to your feline friend. While these plants are beautiful and trendy, they can cause discomfort and health issues if your cat decides to nibble on them.
